Museum strings together 30 old Mac minis for replica of most successful supercomputer, builds something more powerful than the original

What's better than giving the hardware you already own a fresh lease on life? Dedicating your older tech to resurrecting even older supercomputers.

At least, that's if you ask the Museo de Historia de la Computación in Spain. The hardware history museum recently used 30 Mac Minis dating between 2012 and 2014 to resurrect the Cray-1 supercomputer (via Ars Technica).

Debuting in the bygone year of 1976, the Cray-1 is noted for its striking C-shaped cabinet. However, what's arguably most impactful about the new display is that its composite parts make it technically more powerful than the original machine.

The museum's exhibit features five quad-core i7s, and 25 dual-core i5s, resulting in a total of 70 cores to play with. The 30 Mac Minis run on Mojave, leveraging MacOS' Message Passing Interface to pass off computing tasks between them. When all of these cores were online during testing, the exhibit achieved 1.5 teraflops.

The original Cray-1 had a 64-bit, 80 …
